Abstract: The national standards for injection mould bases were compared with the earlier editions. The way to establish standard mould base library based on layout file was mainly introduced. Firstly, the layout file and the parts library for injection mould base were established. Then the corresponding parts were declared to the layout file so that a set of mould base could be converted to a series to call easily.

Key words: Pro/Engineering software, injection mould, standard mould base, layout file, family table
